I doubt they would do this, but it would be great if you could just pay a discounted price for "Infinty 2" and just download it straight to your console. They know that the people paying for it have already purchased the figures.
I got Target to match both Walmart's price and TRU'S BOGO 50% off on the 3-packs, so it's worth trying if you don't have them yet (you'll need the flyer from TRU).
